Question

测试了我已编译的codemirror脚本包，它独立工作，没有别的，但是当我尝试使用gentelella主题中的元素时，它加载没有错误，但是在textarea的隐藏中， codemirror本身是隐藏的。如果我使用Chrome调试器，我可以使代码镜像可见的唯一方法是通过添加style="display: block !important;"来编辑textarea

以下是我用于gentelella主题的代码：

这是我查看页面时得到的结果：

如果我按上述方式更改textarea的样式：

一切正常但除了我无法摆脱textarea（见下图）。

即使我将样式应用于textarea（在chrome live中使用相同的方式）将其重新定位到屏幕外，它实际上最终会重新定位CodeMirror块，并且textarea仍然存在。（示例样式：position: absolute; top: -1000;）

唯一不属于gentelella主题的自定义脚本如下：

codemirror-extras.js

这是使用CodeMirror Builder构建的，并选择了以下选项：

   Version: HEAD

   CodeMirror Library:
   - codemirror.js
   Modes:
   - css.js
   - htmlembedded.js
   - htmlmixed.js
   - javascript.js
   - markdown.js
   - php.js
   - sql.js
   - vb.js
   - vbscript.js
   - xml.js
   Add-ons:
   - active-line.js
   - brace-fold.js
   - closebrackets.js
   - closetag.js
   - comment-fold.js
   - css-hint.js
   - dialog.js
   - foldcode.js
   - foldgutter.js
   - html-hint.js

   - jump-to-line.js
   - markdown-fold.js
   - match-highlighter.js
   - matchbrackets.js

   - overlay.js
   - search.js
   - searchcursor.js
   - show-hint.js
   - sql-hint.js
   - xml-fold.js
   - xml-hint.js

init.js

这只是用一些选项初始化CodeMirror。

        if (tok.type == "string" && (!/['"]/.test(tok.string.charAt(tok.string.length - 1)) || tok.string.length == 1)) return false;

Answer 1

使用 x_content 或 col-md - *

添加div

CodeMirror隐藏了它在Gentelella主题中挂钩的TextArea时消失了
